“…Those with nI latency > 12.9 ms (mean + 2SD) were interpreted as delayed responses, probably due to incomplete maturation of the otolithicocular reflex. For adults aged >60 years old, prolonged latencies and decreased amplitude of oVEMPs can be observed [64].…”

“…Previously, we had reported that all healthy subjects in age groups of 20-29, 30-39, 40-49, and 50-59 years exhibited 100% response rates of present oVEMPs elicited by BCV stimuli [Tseng et al, 2010]. In this study, a control group from healthy subjects with age and sex matched to the MD group also showed 100% present Fpz oVEMPs and present Fz oVEMPs (Table 1).…”

This study investigated ocular vestibular-evoked myogenic potential (oVEMP) tests via Fpz and Fz taps to assess the role of the frontal sinus in mediating oVEMP elicitation. Forty healthy subjects and 80 patients with Ménière disease (MD) underwent a series of oVEMP tests via a minishaker tapping at the Fpz and Fz sites in a randomized order. Response rates of oVEMP test via various tapping sites were compared. Dimensions of the frontal sinus were measured via CT scan. A significantly negative correlation between the age and height of the frontal sinus was noted, and the cutoff age for discriminating present and absent Fpz oVEMPs in MD patients was 52 years. Additionally, oVEMPs by Fpz tapping were more efficiently presented in males than females, likely because of the greater resonance by the larger height of the frontal sinus in males (3.88 ± 0.68 cm) than females (3.42 ± 0.67 cm). In conclusion, the height of the frontal sinus plays a role in mediating the elicitation of oVEMPs. The oVEMPs could be easily elicited by the first-order bone vibration (Fpz/Fz tapping) coupled with the second-order resonance effect (with a high extent of the frontal sinus). Thus, initial tapping at the Fpz site is suggested. If it fails, try the Fz site for screening the oVEMPs.

“…The reason probably is because many patients were elderly (>65 years old) who had deteriorated VEMP responses due to the aging process [27]. Nevertheless, no significant difference existed in the percentages of abnormal oVEMP/cVEMP responses before and after treatment (p > 0.05; table 2).…”

Background: Vestibular assessment in patients with acoustic tumor (so-called vestibular schwannoma, VS) via ocular vestibular-evoked myogenic potential (oVEMP) and cervical VEMP (cVEMP) tests are not often discussed in the neurosurgical literature. Objectives: This study conducted physiological and morphological assessments for VS patients before and after CyberKnife radiosurgery. Methods: Twenty patients with unilateral VS underwent a battery of tests comprising facial nerve function test, audiometry, and caloric, oVEMP and cVEMP tests before and 2 years after CyberKnife treatment at a mean dosage of 18 Gy in 3 fractions. Results: The abnormal percentages of caloric, oVEMP and cVEMP tests did not significantly differ before and after Cyberknife treatment, indicating that preservation of the superior and inferior vestibular nerves can be achieved after radiosurgery. Median tumor volumes, 1.49 cm³ before treatment versus 0.97 cm³ at 2 years after treatment, differed significantly. Conclusions: The use of oVEMP and cVEMP tests in VS patients before stereotactic radiosurgery may help to evaluate the tumor origin from the superior or inferior vestibular nerve. It takes a short time and costs less, and it would be practical to make this a routine examination in VS patients having stereotactic radiosurgery.

Aging Effect on the Ocular Vestibular-Evoked Myogenic Potentials

Abstract: Aging effect (> 60 years old) on the oVEMPs includes reduced response rate, prolonged nI and pI latencies, and decreased nI-pI amplitude. Thus, age factor should be taken into consideration when interpreting the oVEMP results.
